CURVED HAT-STAY-FLANGING MACHINE.

SPECIFICATION forming part of Letters Patent No. 697,871, dated April15, 1902.

Application filed December 19, 1901. $erial No. 86,621. No 111011 1 T0(LZZ whom it may concern.-

Be it known that we, ANTON E. NIELSEN and FISCHER BENTSEN, citizens ofthe United States, and residents of the city of New York, borough ofBrooklyn, in the county of Kings and State of New York, have invented anew and Improved Curved-I-Iat-Stay-Flanging Machine, of which thefollowing is a full, clear, and exact description.

The object of the invention is to provide a new and improvedhat-stay-flangin g machine, more especially designed for fianging theundulating edges of tubular articles, such as paper supports or staysfor nesting hats.

The invention consists of novel features and parts and combinations ofthe same, as will be more fully described hereinafter and then pointedout in the claims.

A practical embodiment of the invention is represented in theaccompanying drawings, forming a part of this specification, in whichsimilar characters of reference indicate corresponding parts in all theviews.

Figure 1 is a side elevation of the improvement with parts broken out.Fig. 2 is a front elevation of the same. Fig. 3 is a sectional plan viewof the same on the line 3 3 of Fig. 2, and Fig. a is a perspective viewof part of the finished article.

On a base A are erected standards A and A having vertical guideways forbearings 13 B, resting on screws 0, held on the base A and adapted toallow of vertically adjusting the bearings B B to bring the same inproper alinement. In the bearings 13 B is j ournaled a shaft 1),carrying at one end a crank-arm E for turning the shaft'D, and on theother end of the latter is secured a crimping-die F, operating inconjunction with a crimping-die F and a guide-plate or former G to crimpthe edge of the blank to be treated, as hereinafter more fullydescribed. On a shaft H is secured a gear-wheel I, in mesh with agearwheel 1, fastened to the shaft D, so that when the latter is rotatedthe gear-wheel I rotates the gear-wheel I and shaft H, so that the twocrimping-dies F and F are rotated in unison. The shaft H, on which thedie F is secured, is journaled in bearings J J, held in the standards AA the bearing J being hung on trunnions or centers J 2 and the bearing Jbeing mounted on springs K, supported from the bearing B. On top of thebearing J are an ranged springs K, engaged by a plate K adapted to bepressed by a cam-lever L, fulcrumed at L to the top of the standard A,the said cam-lever L when thrown over into an inactive position restingon a support L attached to the standard A. When the camlever L is in theposition shown in the drawings, the springs K are compressed and thebearing J is held in such a position that the shaft H extendsapproximately parallel to the shaft D, and when the cam-lever L is swunginto an open position the bearingJ is caused to slide upwardly by theaction of the springs K to move the shaft H into an angular position andthe die F into the uppermost position for conveniently inserting theblank between the dies F F. When the blank has been inserted, the leverL is thrown back into an active position, so as to cause the plate K andsprings K to force the bearing J downwardly against the tension of thesprings K to hold the shaft H and die F in a normal active position.

The dies F and F are disk-shaped and are provided with registeringannular bevels F F and registering grooves F F so that when the dies Fand F engage a paper blank the latter extends between the two bevels F Fand into the registering grooves F F, which latter then form a circularopening between the dies, as will be readily understood by reference toFig. 1, as each of the grooves is halfround in cross-section.

The guide-plate Gr is formed on its back with an upturned andforwardly-projecting flange G, as plainly indicated in Figs. 1 and 3, toallow of properly guiding the blank for ward between the dies F and F,the mouth or entrance G of the guide-plate being flaring and the bottomof the plate segmental, so as to readily accommodate the tubular blankto be crimped at its undulating edges. The guide-plate G is adjustablysecured by screws N to a bracket A on the standard A, and the rear edgeof the said guide-plate abuts against screw-rods N,screwing in thebracket, to allow of adjusting the guide-plate at the time thefastening'screws N are loosened.

In using the machine the operator first swings the cam-leverL into anopen position to allow of insertingthe edge of a tubular blank betweenthe dies F F, the edge abutting against the flange G of the guide-plateG. When this has been done, the operator swings the cam-lever L into,the position shown in Figs. 1 and 2, so that the blank is firmly engagedbetween the dies F and F The crank-arm E is now turned, so as to rotatethe dies F F in unison,wl 1erebythe annular edges of the dies betweenthe bevels F F and the grooves F F crease the paper blank a distancefrom the edge thereof throughout the length of the blank, and when theblank is passed a second time between the dies F F the creased portionis causedto bend upwardly and inwardly, owing to the action of theflange G and'the. grooves F F, so that the. edge is properly flangedback onto the body of the blank, aswillbe readily un-.

derstood. by reference toFig. 4. Pa'ssingthe.

blank twice. in successionthrough the. machine usually completestheflanging operation; but it may berun throughthe machine more thantwice if deemed necessary. When theflanging operation is completed,- theoperator swings the camelever L forwardly to separate .thedie F fromthedie F andto allowof removing the flanged article. By thearrange mentdescribed the operator in holding the blank can readily guide the samealong the.

guide-plate G, accordingto the. undulation of the edge of the. blank,sothat the edgeis properly flanged whether thesame is straight.

or undulated. The-machine is very simple and durablev in constructionand can be read ily manipulated without. the use of skilled labor toproperly flange the edgesof tubular or other bodies.

Having thus described our invention, we

claim as new and desire to secure by Letters Patent- 1. Afianging-machine, comprising a pair of revoluble dies, and a guide-plateat the entrance side of the dies for guiding. the edge of an articlev tothe. dies, the said guide-plate having an upturned and overhangingflange forming a taperingguideway with outwardlyfiaring mouth to guidethe article to the dies and to assist in turning over the edge of theblank sufficiently for the. revoluble dies to complete the crimping, thebottom of the guide-plate being arched to accommodate tubular articlesof different diameters, as set forth.

2. Afianging-machine, comprising a pair of revoluble dies, a guide-plateat the entrance sideof the dies for guiding the edge of an article tothe dies, the said guide-plate having a segmental body-portion and anupturned and overhanging flange forming a tapering guideway withoutwardly-flaring mouth to guide the articleto'the dies and to assist inturning over the edge of the blank sufficiently for the revoluble diesto complete the crimping, and means for adjusting the guide-platerelatively to the said dies, as set forth.
